Published The next generation of solar energy collectors could be rocks
(via sciencedaily.com) Original source The next generation of sustainable energy technology might be built from some low-tech materials: rocks and the sun. Using a new approach known as concentrated solar power, heat from the sun is stored then used to dry foods or create electricity. A team has found that certain soapstone and granite samples from Tanzania are well suited for storing this solar heat, featuring high energy densities and stability even at high temperatures.

(via sciencedaily.com) Original source Ultrafast laser physicists from the attoworld team have gained new insights into the dynamics of electrons in solids immediately after photoinjection.
Published Quantum scientists accurately measure power levels one trillion times lower than usual
(via sciencedaily.com) Original source Scientists have developed a nanodevice that can measure the absolute power of microwave radiation down to the femtowatt level at ultra-low temperatures -- a scale trillion times lower than routinely used in verifiable power measurements. The device has the potential to significantly advance microwave measurements in quantum technology.
Published Quantum matter breakthrough: Tuning density waves

Published Demystifying vortex rings in nuclear fusion, supernovae
(via sciencedaily.com) Original source Better understanding the formation of swirling, ring-shaped disturbances -- known as vortex rings -- could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to becoming a viable energy source. A mathematical model linking these vortices with more pedestrian types, like smoke rings, could help engineers control their behavior in power generation and more.
Published Uncovering universal physics in the dynamics of a quantum system
(via sciencedaily.com) Original source New experiments using one-dimensional gases of ultra-cold atoms reveal a universality in how quantum systems composed of many particles change over time following a large influx of energy that throws the system out of equilibrium.

Published Watch these cells rapidly create protrusions for exploration and movement
(via sciencedaily.com) Original source In order to move, cells must be able to rapidly change shape. A team of researchers show that cells achieve this by storing extra 'skin' in folds and bumps on their surface. This cell surface excess can be rapidly deployed to cover temporary protrusions and then folded away for next time.
Published Curved spacetime in a quantum simulator
(via sciencedaily.com) Original source The connection between quantum physics and the theory of relativity is extremely hard to study. But now, scientists have set up a model system, which can help: Quantum particles can be tuned in such a way that the results can be translated into information about other systems, which are much harder to observe. This kind of 'quantum simulator' works very well and can lead to new insights about the nature of relativity and quantum physics.

(via sciencedaily.com) Original source Researchers have developed a new class of integrated photonic devices -- 'leaky-wave metasurfaces' -- that convert light initially confined in an optical waveguide to an arbitrary optical pattern in free space. These are the first to demonstrate simultaneous control of all four optical degrees of freedom. Because they're so thin, transparent, and compatible with photonic integrated circuits, they can be used to improve optical displays, LIDAR, optical communications, and quantum optics.
